Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server version    *
    *                  6.1 users of Java Server Faces (JSF).       *
    ****************************************************************
    * PROBLEM DESCRIPTION: BeanInfoManager instances in the        *
    *                      JSF's BeanInfoManager static hashmap    *
    *                      are not removed when an application     *
    *                      is stopped which leads to               *
    *                      Classloaders not being garbage          *
    *                      collected.                              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    JSF's BeanInfoManager keeps a hashmap of the classes it has
    instances of. This hashmap is not cleaned up when applications
    are stopped which causes it to hold onto references of classes
    from applications that have stopped and possibly even
    restarted. This prevents the Classloaders which loaded those
    classes from being garbage collected.
    

Problem conclusion

  • Method was added to BeanInfoManager that removes all the
    entries for a given classloader. The JSF code was also updated
    to call that method when applications are stopped.
    
    The fix for this APAR is currently targeted for inclusion in
    fixpack 6.1.0.21.  Please refer to the Recommended Updates
